In a previous communication we reported on the isolation and structure elucidation of 3`, 4`, 7-trihydroxyflavone, α-spinasteryl-D-glucoside, acacic acid lactone and machaerinic acid methylester from the stembark of Albixzia julibrissin (Leguminosae)...
In a previous communication we reported on the isolation and structure elucidation of 3`, 4`, 7-trihydroxyflavone, α-spinasteryl-D-glucoside, acacic acid lactone and machaerinic acid methylester from the stembark of Albixzia julibrissin (Leguminosae). In this communication the isolation of two sapogenins; acacigenin B, mp 278˚∼81˚, [α]_D+56.7˚and sapogenin B, mp 240˚, [α]_D+14.75˚ will be presented. This is the second report of acacigenin B, a monoterpene ester of acacic acid, from plant source.
